CROSS REFERENCE TO RELATED APPLICATIONS

This is a continuation application of U.S. patent application Ser. No.14/693,207 (filed on Apr. 22, 2015 and claims priority to U.S.Provisional Patent Application No. 61/982,717, filed on Apr. 22, 2014),the contents of all of which are hereby incorporated by reference intheir entirety, including the contents and teachings of any referencescontained therein.

BACKGROUND

The present disclosure relates generally to surgical systems, devices,and methods, and more specifically, relates to systems and devices foruse in performing Minimally Invasive Surgical (MIS) procedures, andmethods of configuring such surgical systems and devices.

With the advancement of medical science and technology, mostconventional open surgical procedures, which require large incisions toa patient in order to view and access inside the body cavity of thepatient, have been largely replaced with MIS procedures.Computer-assisted and/or robotic surgical technology has contributed toadvancements in MIS so as to translate a surgeon's desired actions,including movements of the surgeon's fingers and hands, into movementsof laparoscopic instruments inside the body cavity of a patient.

BRIEF SUMMARY

Despite recent developments in modern medical science, it is recognizedin the present disclosure that one or more problems are encountered inmodern surgical technology and methodology, including MIS. For example,a typical MIS procedure requires multiple incisions to a patient inorder to allow access via the incisions for the insertion of a cameraand various other laparoscopic instruments into the body cavity of thepatient.

As another example, it is recognized in the present disclosure thatsurgical robotic devices, including surgical robotic arms, oftentimesencounter difficulties during surgical procedures due to insufficientanchoring and/or reactive forces to stabilize against forces that aredesired and/or necessary to be applied during surgical actions.

It is also recognized in the present disclosure that surgical roboticsystems face difficulties in providing an instrument, such as a cuttingor gripping instrument attached to the end of a surgical robotic arm,with access to all or even most parts, areas, and/or quadrants ofabdominal cavity of a patient. That is, after the surgical robotic armis inserted in the abdominal cavity of the patient and ready to performa surgical action, the instrument attached to the end of the surgicalrobotic arm is typically limited to access only certain parts, areas,and quadrants of the abdominal cavity of the patient.

In yet another example of a problem encountered by surgical roboticsystems, surgical robotic systems typically provide only between one totwo surgical robotic arms per access or opening (such as an incision ora natural orifice) of the patient. In this regard, one or moreadditional incisions will be required for the insertion of a camera andvarious laparoscopic instruments into the abdominal cavity of thepatient.

DETAILED DESCRIPTION

Example embodiments will now be described with reference to theaccompanying drawings, which form a part of the present disclosure, andwhich illustrate example embodiments which may be practiced. As used inthe present disclosure and the appended claims, the terms “exampleembodiment,” “exemplary embodiment,” and “present embodiment” do notnecessarily refer to a single embodiment, although they may, and variousexample embodiments may be readily combined and/or interchanged withoutdeparting from the scope or spirit of example embodiments. Furthermore,the terminology as used in the present disclosure and the appendedclaims is for the purpose of describing example embodiments only and isnot intended to be limitations. In this respect, as used in the presentdisclosure and the appended claims, the term “in” may include “in” and“on,” and the terms “a,” “an” and “the” may include singular and pluralreferences. Furthermore, as used in the present disclosure and theappended claims, the term “by” may also mean “from,” depending on thecontext. Furthermore, as used in the present disclosure and the appendedclaims, the term “if” may also mean “when” or “upon,” depending on thecontext. Furthermore, as used in the present disclosure and the appendedclaims, the words “and/or” may refer to and encompass any and allpossible combinations of one or more of the associated listed items.

It is recognized in the present disclosure that, despite recentdevelopments in medical science and technology, one or more problems areencountered in surgical technology and methodology, including MIS. Forexample, a typical MIS procedure requires multiple incisions or a singleincision of up to 35 mm each to a patient in order to allow access forthe insertion of a camera and various other laparoscopic instrumentsinto the abdominal cavity of the patient. It is recognized in thepresent disclosure that such rather large and multiple incisions imposeseveral in-surgery and post-surgery disadvantages, undesirableconsequences, and/or complications to the patient, including excessiveblood loss, large and multiple wound/scar sizes, and longer healingtimes, thereby necessitating longer hospitalization periods.

In addition to the aforementioned disadvantages pertaining to themultiple and rather large incisions, it is recognized in the presentdisclosure that surgical robotic systems, including surgical roboticarms (and those instruments attached to them), developed for performingrobotic-assisted MIS surgical procedures also suffer from one or moreproblems. For example, it is recognized herein that a major technicalchallenge for a surgical robotic system is the difficulty in providingsufficient anchoring and/or reactive forces to stabilize against forcesthat are desired and/or necessary to be applied to the patient by thesurgical robotic system during a surgical action. In this regard,certain surgical actions for known surgical robotic systems may requiretremendous effort and time, and may not be performed properly or at allas a result of the problem of insufficient anchoring and/or reactiveforces.

Another example of a problem recognized in the present disclosure asbeing encountered by surgical robotic systems is the difficulty inproviding an instrument, such as a cutting and/or gripping instrumentattached to the end of a surgical robotic arm, with access to all oreven most parts, areas, and quadrants of an abdominal cavity of apatient after the surgical robotic system has been set up (or installed)and is ready to perform a surgery. That is, after the surgical roboticarm of the system has been inserted, attached, and properly set up inthe abdominal cavity of the patient and is ready to perform a surgicalaction, the instrument attached to the end of the surgical robotic armis typically limited to access only certain parts, areas, and quadrantsof the abdominal cavity of the patient. It is recognized in the presentdisclosure that such problems result in large from the limited number ofpossible degrees of freedom that can be provided by known surgicalrobotic systems and arms, and more specifically, the limited number ofin vivo degrees of freedom (i.e. the degrees of freedom provided withinan abdominal cavity of a patient) of known surgical robotic systems andarms. In this regard, surgical robotic systems typically provide onlybetween 2 to 4 in vivo degrees of freedom for each surgical robotic arm.

Recent developments to surgical robotic systems attempt to solve theaforementioned problem by providing an additional in vitro degree offreedom (i.e. the degree of freedom provided from outside the body of apatient). It is recognized in the present disclosure, however, that suchrecent developments still do not sufficiently address the difficultiesin providing an instrument attached to the end of a surgical robotic armwith access to all parts, areas, and/or quadrants of the abdominalcavity of the patient after the surgical robotic system has been set upand is ready to perform a surgical action in the abdominal cavity of thepatient.

As another example, surgical robotic systems typically only provide forbetween one to two surgical robotic arms per access or opening (such asan incision or a natural orifice) of the patient. In this regard, whenadditional laparoscopic instruments, such as another surgical roboticarm, a suction tube, and/or a camera, are required to be inserted intothe abdominal cavity of the patient, one or more additional openings(incisions) are required for the patient.

In respect to surgical robotic arms, surgical teams often encounterdifficulties with properly inserting and removing surgical robotic armsinto and out of a body cavity of the patient. Specifically, sincesurgical robotic arms generally have at least one joint and two armsegments, the insertion of a surgical robotic arm into the body cavityoftentimes results in a portion of the surgical robotic arm (such as theend connected to an instrument, such as a cutting tool) coming intocontact with and damaging patient tissue. Likewise, the removal of asurgical robotic arm from the body cavity oftentimes results in aportion of the surgical robotic arm coming into contact with anddamaging patient tissue. This problem becomes compounded when a surgicalprocedure or system attempts to employ more than one surgical roboticarm through a single port.

It is also recognized in the present disclosure that surgical roboticsystems oftentimes face problems in respect to the heating up of one ormore components during a surgical action, such as the heating up oflaparoscopic optics (such as a camera), lighting elements, and othercomponents. For example, the increased temperature of such componentsmay possibly impose in-surgery and/or post-surgery damage orcomplications to patient tissues that come into contact with suchcomponents.

In yet another example problem, surgical procedures and systemsoftentimes encounter problems with providing and maintaining sufficientinsufflation of a body cavity (such as an abdominal cavity) throughout asurgical procedure.

Another example problem encountered by surgical procedures and systemspertains to the tendency for laparoscopic optics (such as a lens of acamera) and/or lighting elements to encounter contamination and/orpartial or complete blockage during a surgical procedure due to fogging,tissue debris, liquids (such as blood), and/or other particlesaccumulated before, during, and/or after insertion of such componentsinto the body cavity. In this regard, visibility within a body cavityvia such laparoscopic optics and lighting elements may become reduced,deteriorated, or even completely blocked as a result.

Surgical systems, devices, and methods, including those for use inrobotic MIS, are described in the present disclosure for addressing oneor more problems of known surgical systems, devices, and methods,including those described above and in the present disclosure. It is tobe understood that the principles described in the present disclosurecan be applied outside of the context of MIS and/or laparoscopicsurgery, such as performing scientific experiments and/or procedures inenvironments that are not readily accessible by humans, including in avacuum, in outer space, and/or under toxic and/or dangerous conditions,without departing from the teachings of the present disclosure.

The Surgical System (e.g., Surgical Device 100)

An illustration of an example embodiment of a surgical device 100operable to be inserted into an abdominal cavity of a patient through asingle access or opening (such as single umbilical incision or a naturalorifice, hereinafter referred to as an “opening”) of the patient andanchored in or about the same opening is depicted in FIG. 1. Thesurgical device 100 may comprise a port assembly 110, an instrument armassembly 130, and a camera arm assembly 120.

The external anchor 200 may be operable to securely fixthe position and/or orientation (hereinafter “position”) of the portassembly 110 in or about the single opening of the patient, and may alsobe operable to provide sufficient anchoring and/or reactive forces tostabilize against forces desired and/or necessary to be applied by atleast one or more instruments of the surgical device 100, including theinstrument arm assembly 130, during a surgical action or procedure. Theexternal anchor 200, including the controllable swivel assembly 1300 (asillustrated in FIG. 13), may also be operable to cooperate with the portassembly 110 to provide one or more in vitro degrees of freedom. Inexample embodiments, the one or more in vitro degrees of freedom mayinclude a torsional movement, pivotal movement, and/or other movementsof the port assembly 110 relative to the external anchor 200. Forexample, a torsional movement of the port assembly 110, as illustratedby arrow A in FIG. 2B, may allow one or more attached instruments,including an instrument arm assembly 130, to re-position during asurgical procedure (i.e. after set up or installation) so as to accessother parts, areas, and/or all quadrants of the abdominal cavity of thepatient. As another example, a pivotal movement of the port assembly110, as illustrated by arrow B in FIG. 2B, may allow the port assembly110 to be positioned in one of a plurality of angles with respect toopening of the patient, and may also allow attached instruments,including the instrument arm assembly 130, to re-position during asurgical procedure (i.e. after set up or installation) so as to accessdistal areas of the abdominal cavity of the patient. The other jointportions of the external anchor 200 may also be operable to cooperateand/or assist in desired movements of the port assembly 110. Theexternal anchor 200 may be anchored to one or more stationary objects,such as a side rail 300 of a surgical table/bed illustrated in FIG. 2A.FIG. 13 illustrates other example movements that provide for additionalin vitro degrees of freedom via an example embodiment of thecontrollable swivel assembly 1300.
